Deep foundation pipe piles, structural hollow sections, and tubular columns for port construction, bridges, high-rise buildings, and industrial infrastructure. ASTM A252, EN 10219, and EN 10210 compliant with full structural certification.
Steel pipe piles and structural hollow sections are the backbone of modern civil engineering and construction. From the deep foundations that support skyscrapers to the massive piling required for port and bridge construction, Sino East Steel provides the full range of structural steel pipe products with the certifications and quality documentation required by structural engineers and contractors worldwide.
Pipe piles transfer structural loads through weak surface soils to competent bearing strata below. Our ASTM A252 pipe piles are available in Grades 1, 2, and 3 with diameters up to 120 inches for the most demanding foundation requirements. Open-ended piles can be driven through dense soils and filled with concrete for composite action. Closed-ended piles with driving shoes provide maximum end-bearing capacity.
Port infrastructure — berthing dolphins, mooring piles, fender piles, and jetty structures — requires steel pipe with proven performance in the marine environment. Our large-diameter SSAW and LSAW piles with heavy-duty coatings resist corrosion in the splash zone and submerged zones, providing decades of reliable service under the most aggressive conditions.
Bridge piers, abutments, and foundation caissons demand the highest structural integrity. Steel pipe piles for bridge foundations are manufactured with full-length UT testing of welds and certified Charpy impact properties. Combined wall systems using pipe piles and sheet piles create efficient, cost-effective bridge abutments and retaining structures.
Tubular steel columns offer superior structural efficiency — higher radius of gyration, better buckling resistance, and clean architectural appearance. Our EN 10219 and EN 10210 structural hollow sections are used in stadiums, airports, exhibition halls, and high-rise buildings where exposed structural steel is a design feature.
